“…Um caso é o da eficiência do uso antibacteriano de extratos de folhas e frutos (Mohanasundari et al, 2007;Bhosale & Sutar, 2015), sendo que os principais metabólitos secundários encontrados em folhas, ramos, frutos e sementes são alcaloides, flavonoides, compostos glicosídeos cardíacos, antraquinonas e saponinas (Bhosale & Sutar, 2015). Tricomas presentes principalmente nas flores, frutos, brácteas e estípulas, secretam resina que apresenta defesa contra lagartas de Dione juno juno (Boiça Júnior et al, 2008).…”

RESUMO Objetivou-se, com este trabalho, determinar o tamanho de amostra para análise de caracteres físicos e químicos de frutos maduros de maracujá-fedorento (Passiflora foetida). Foram colhidos, aleatoriamente, 150 frutos de plantas cultivadas em casa de vegetação. Em laboratório, esses frutos foram mensurados quanto a 12 caracteres (comprimento longitudinal; diâmetro equatorial; massa de fruto; massa de casca; massa de polpa; rendimento de polpa; peso de sementes por fruto; número de sementes por fruto; massa de sementes por fruto; acidez titulável; sólidos solúveis e ratio), sendo calculadas as medidas de tendência central e de dispersão e verificada sua normalidade. Determinou-se o intervalo de confiança bootstrap percentil, a partir da simulação de tamanho 4.000, para 150 tamanhos de amostra (1, 2, ..., 150 frutos) de cada caractere mensurado. Os caracteres físicos e químicos analisados em frutos maduros de P. foetida apresentam diferentes precisões experimentais e requerem diferentes tamanhos de amostra. Para o comprimento longitudinal, por exemplo, o diâmetro equatorial e a relação entre estes, seis frutos são suficientes para a estimação da média com um erro de estimação de 5% da média. Se forem considerados todos os caracteres físicos e químicos de frutos maduros, analisados neste trabalho, são necessários no mínimo 39 frutos, assumindo-se erro de 10% da estimativa da média.

“…Five saponins were described from P. alata leaves (Reginatto et al, ), the most abundant being quadranguloside, also found in P. quadrangularis (Reginatto et al, ). D. juno larvae had 100% mortality when fed with P. alata leaves (Boiça Júnior, Angelini & De Oliveira, ) and larvae of Heliconius erato and Heliconius charithonia did not consume P. quadrangularis leaves in feeding assays (Smiley, ). Consequently, quadranguloside could be effective against some heliconiine herbivores.…”

The arms race between heliconiine butterflies and Passiflora plants – new insights on an ancient subject

Heliconiines are called passion vine butterflies because they feed exclusively on Passiflora plants during the larval stage. Many features of Passiflora and heliconiines indicate that they have radiated and speciated in association with each other, and therefore this model system was one of the first examples used to exemplify coevolution theory. Three major adaptations of Passiflora plants supported arguments in favour of their coevolution with heliconiines: unusual variation of leaf shape within the genus; the occurrence of yellow structures mimicking heliconiine eggs; and their extensive diversity of defence compounds called cyanogenic glucosides. However, the protection systems of Passiflora plants go beyond these three features. Trichomes, mimicry of pathogen infection through variegation, and production of extrafloral nectar to attract ants and other predators of their herbivores, are morphological defences reported in this plant genus. Moreover, Passiflora plants are well protected chemically, not only by cyanogenic glucosides, but also by other compounds such as alkaloids, flavonoids, saponins, tannins and phenolics. Heliconiines can synthesize cyanogenic glucosides themselves, and their ability to handle these compounds was probably one of the most crucial adaptations that allowed the ancestor of these butterflies to feed on Passiflora plants. Indeed, it has been shown that Heliconius larvae can sequester cyanogenic glucosides and alkaloids from their host plants and utilize them for their own benefit. Recently, it was discovered that Heliconius adults have highly accurate visual and chemosensory systems, and the expansion of brain structures that can process such information allows them to memorize shapes and display elaborate pre-oviposition behaviour in order to defeat visual barriers evolved by Passiflora species. Even though the heliconiine-Passiflora model system has been intensively studied, the forces driving host-plant preference in these butterflies remain unclear. New studies have shown that host-plant preference seems to be genetically controlled, but in many species there is some plasticity in this choice and preferences can even be induced. Although much knowledge regarding the coevolution of Passiflora plants and heliconiine butterflies has accumulated in recent decades, there remain many exciting unanswered questions concerning this model system.

“…Insect pests, including Dione juno juno Cramer, 1779 (Lepidoptera: Nymphalidae), feed on leaves and branches, reducing the production of the yellow passion fruit Passiflora edulis Sims (Boiça Júnior et al, 2008). This pest is mainly controlled with chemical insecticides that can contaminate food, water, and soil, besides reducing populations of natural enemies and facilitating the emergence of resistant insects (Amatuzzi et al, 2018;Costa et al, 2020).…”
